Walter P Moore provided structural engineering design services for this 80-story high-rise office tower in Saudi Arabia. At 400 meters tall and 1,991,000 square feet, this world class office tower is to be the landmark project of the new King Abdullah Financial District in Northern Riyadh.
Walter P Moore analyzed over 20 lateral systems for the tower during a six month design period, and ultimately recommended a composite scheme. In the composite scheme, a central Y-shaped concrete core works in conjunction with a composite perimeter braced frame. No columns are vertical, as they sweep in and out with the faceted curtain wall. In keeping with Walter P Moore’s theme of integration of building systems, the sloping braces and columns are fully integrated with the façade which maximizes lettable floor area and minimizes structural materials.

During the structural system selection phase, Walter P Moore performed a carbon emissions comparison of multiple schemes. Even though the composite scheme would require a significant amount of structural steel to be imported for the project, the required concrete in the composite scheme was 40% less than that of an all concrete scheme which resulted in approximately 30% less total embodied carbon emissions for the structural frame.

Cyril Sweett manages single largest foundation pour in history of Saudi Arabia

Cyril Sweett International (Cyril Sweett) is pleased to announce that the concrete pour on the foundations of Saudi Arabia's prestigious Capital Market Authority (CMA) tower has been successfully completed, following a deep excavation of over 30 metres and over 4,000 tonnes of steel reinforcements.

The pour was executed by the Saudi Bin Laden Group (SBG), under direct management of Cyril Sweett. The CMA tower is the tallest tower in the Kingdom of Saudi Arabia currently under construction and this was the single largest concrete pour recorded in the history of the Kingdom to date. With one and half consecutive days of concrete being pumped into the raft foundation, 13,000 cubic metres of concrete mix were used to complete the 4.5 metre high foundation.

Commenting on the pour, Des Pike, Project Director of Cyril Sweet, said, "The concrete pour was scheduled to last 42 hours but was successfully completed within 36 hours. Throughout the operation, mobile truck mixers were arriving on site at an average of one every 90 seconds, a significant logistical feat in itself. This is a great achievement for all parties involved who worked continuously around the clock to ensure its success."

Dr. Said Rabiah, CMA Project Department Manager, said, "We are delighted to see the foundations of the CMA Tower have been completed on schedule. The success of this massive undertaking was the result of the remarkable efforts and collaboration of all parties involved. This could not have been achieved without the strong leadership of Cyril Sweett's project management team. I would like to thank the entire project team for achieving this monumental task and very significant milestone."

The CMA tower is the focal project of the King Abdullah Financial District and when completed will soar 385m above ground level. Designed by renowned American architects, HOK, and leading consulting firm Omrania & Associates, the building combines architectural ingenuity with the very best in environmental credentials to achieve a Gold LEED standard.

Guess what guys, the building has been under construction since last June. This picture of the building raft foundation last Augest Thanks to our friend Lonny who works there, otherwise we wouldn't have known about it.

"The last photo shows the CMA Tower raft foundation preparation. The contractor has placed concrete for the bottom and sides to create a neat level and plumb surface to construct the raft foundation for the tower on. Even though this building is not part of our scope of work here, I was able to meet with the designers on another mater and got a close look at the foundation and the building. The foundation has three distinct locations where there will be super columns. These areas of the raft foundation are designed to support the huge columns independently. If you look at the photo you will see the locations at 1/3 the distance around the foundation area, one directly in front of me, the others to the left and right. The columns will measure 3 meters wide by 3.6 meters thick. Pretty big. There is an excellent discussion about the design of the building on engineer Walter P Moore’s site. There is also discussion about the Samba Tower on the site as well. The Samba Tower will be in the Financial Plaza near the CMA and is being constructed by El-Seif."
:lol: All this happened way back in the summer.

found this great detailed map:

Use the site plan to find the exact position of each project. Links goes to Urbika, an excellent site we use to try to get an overview of all the projects.

This is mainly made for my self to the overview while i search for information.

Then i have a few missing plots i don't know anything about, but according to the map there are a building with design ready there.

Would be nice if someone could fill me out here. Heights on most buildings are missing. Need better renderings for a lot of them as well.

i really like the layout of that master plan, the only problem i have is that massive freeway surrounding it. i really hate how masterplans isolate themselves from everything, it's just plain... dumb. i mean, it'd make more sense to bury the freeway and start low-rises (i mean like low-low-rises, like 6-10 stories sort of like downtown beirut but with different styles) all around with alleys so people can walk those 300 or so meters rather than drive. it'd be perfect and the distance between the buildings would create shadows for comfortable short-distance walks.

no one walks in saudi.. the weather here is not as nice as baurite, everyone have a car, even having a metro will not work, (gas is CRAZY CHEAP like water)...
but this area (along side universities) will be one of the few urban areas where ppl will actually walk. its a new experience in saudi. (ppl will drive to the district) most of the roads in the district are underground, and ppl will walk between buildings in what is called (skywalks) + there will be a tiny metro inside
